Warming Oceans Likely To Raise Sea Levels 30cm By End Of Century – Study

The world’s oceans are warming at a faster rate than previously estimated, new research has found, raising fresh concerns over the rapid progress of climate change.
Warming oceans take up more space, a process known as thermal expansion, which the study says is likely to raise sea levels by about 30cm by the end of the century, on top of the rise in sea levels from melting ice and glaciers. Warmer oceans are also a major factor in increasing the severity of storms, hurricanes and extreme rainfall.
Oceans store heat so effectively that it would take decades for them to cool down, even in the unlikely scenario that greenhouse gas emissions were halted urgently.
The report, published on Thursday in the journal Science, found that the warming of the oceans was accelerating and was matching the predictions of climate change models, which have shown global temperature rises are likely to lead to extreme weather across the world.
Zeke Hausfather, co-author of the paper and a graduate student at the University of California, Berkeley, said: “While 2018 will be the fourth warmest year on record on the [earth’s] surface, it will most certainly be the warmest year on record in the oceans, as was 2017 and 2016 before that. The global warming signal is a lot easier to detect if it is changing in the oceans than on the surface.”
Oceans absorb more than nine-tenths of the excess energy trapped in the atmosphere by greenhouse gases, and play a key role in regulating the world’s climate.
But the role of oceans in the global climate system was overlooked for many years, in part because of a lack of data and the difficulty of studying the marine environment. Only in recent years have scientists come to realise the full importance of oceans, which have effectively absorbed much of the impact of climate change in recent decades, but are now understood to be reaching their capacity as a buffer.
Separate recently published research extrapolated temperature estimates for the oceans for the past 150 years, and found substantial warming.
Published in the journal Proceedings of the National Academy of Sciences of the United States of America, that research found the total heat taken up by the oceans in the last century and a half was about 1,000 times the annual energy use of the world’s population.
A Guardian analysis of those findings suggested that the amount of energy absorbed by the oceans was equivalent to an atomic bomb per second for the past 150 years. Scientists said this was unsustainable in the long term without seeing further massive effects, including extreme weather, fiercer storms, and sea level rises.
The heating could also affect sea currents around the world, with unpredictable consequences.
Late last year, the Intergovernmental Panel on Climate Change warned that the world would face dire effects from global warming from 2030 unless urgent and drastic measures are taken to reduce greenhouse gas emissions.
The new Science paper analysed four studies published between 2014 and 2017, which corrected for discrepancies between different types of ocean temperature measurements and gaps in measurements.
Satellite monitoring, buoys and ships are all used to gather data on the effect of climate change on the oceans. In the past decade, a network of 4,000 buoys known as Argo has provided an unprecedented data set on the temperature, salinity and acidification of oceans.
By taking the four studies, with different methodologies, into consideration the authors of the new analysis were able to build a fuller picture than was previously possible, with calculations extrapolated back to the 1970s.

Records 'Blown Away' As Rising Power Bill Fears Trigger Solar PV Surge

FairfaxPeter Hannam

New solar energy installations tripled in capacity in 2018 in Australia, with solid growth in rooftop solar eclipsed by a massive increase in utility-sized ventures.
According to data collected by Green Energy Trading, the nation added just over 3775 megawatts of photovoltaic capacity last year, up from 1270MW a year earlier.


Solar panel installations soared to annual records - again - in 2018.
"That's blown away" the previous records, Tristan Edis, director of Green Energy Markets, said. "It's going to have a significant impact on [wholesale] power prices in the middle of the day."
Total installations are forecast by the consultancy to rise another quarter this year to 4700MW.
While 2018 was a year the solar farm came into its own – with more than 2000MW added, half of it in Queensland – rooftop solar for homes and businesses continued to expand at annual rates of more than 40 per cent, the firm estimated, using certificates surrendered by installers.

For residential users, NSW regained the lead as the nation's largest market, with 326MW added, up almost 60 per cent from 2017 levels.
Victoria, though, grew at close to 70 per cent during the year, thanks in large part to a pre-election promise from the Andrews Labor government to support the installation of 650,000 new systems.
Australia late last year passed its two millionth home with solar PV, with installations running at six panels a minute. All up about one in five houses have solar systems, one of the highest penetration rates anywhere.
Domenic Mercuri, chief executive of Solargain, said the lead time for installation was out to as long as 10 weeks in Victoria compared to about half that in other states.
The company grew about a fifth in 2018, swelling its workforce, including contractors, to 220.
"We'd expect to grow another 20 per cent this year," Mr Mercuri said.
Even with the industry's rapid pace and payback times for residential panels dropping to under five years, consumers were becoming more savvy, he said.
"They know the brand they want, the panels, the system size – they're more educated," including wanting to know how long the retailer had been around, Mr Mercuri said.
With signs that retail power prices have started to taper – reducing one accelerant for demand – fresh buyers were appearing on the commercial side, which accounts for about 30 per cent of Solargain's sales, he said.

New growth sector
Green Energy Markets' Mr Edis said businesses looking to add systems of greater than 100 kilowatts of capacity – a segment which more than doubled in 2018 – was emerging as a growth sector.
"We've probably got significant room for growth there in 2019," he said, adding the sector "is only just starting to develop some legs".
One reason for the optimism was many companies had three-year power contracts. About a third of them could expect higher electricity bills this year when they renewed deals that included the effect of the closure in 2017 of Victoria's Hazelwood power plant, making solar PV more attractive.
Wholesale prices in the National Electricity Market may start to decline this year as the impact of the huge increase in solar farm capacity started to take effect, Mr Edis said.
Some of that price influence had so far been masked by a sharp reduction in output from Snowy Hydro plants in anticipation of falling reservoir levels amid the drought.
Assuming dams start to fill up this year and next, the benefit of extra renewable capacity - including the wind and solar farms that will come online in 2019 - should add to downward pressure on wholesale prices, Mr Edis said.

The Biggest Issues For Wildlife And Endangered Species In 2019

The RevelatorJohn R. Platt

It’s going to be a rough year, but we’ll also see some progress.

Wildlife didn’t have an easy go of it in 2018. We lost the last male northern white rhino, the vaquita porpoise continued its slide toward extinction, poachers kept targeting pangolins and other rare creatures, and through it all the Trump administration kept trying to whittle away at key protections for endangered species.
So with that rough bit of recent history, what does 2019 hold?
Well, in most cases it won’t be pretty. There will be more blood, more habitat loss, more legislative attacks and more extinctions — but at the same time, there will also be signs of hope and progress on many levels.
Here are some big issues that experts say we should be watching in 2019:

Climate Chaos
Of course, climate change will continue to threaten species around the world in 2019.
“The impacts of climate change aren’t showing signs of slowing, and this administration refuses to recognize it,” says Charise Johnson of the Union of Concerned Scientists. “Water temperatures are rising, increased flooding, deforestation, fires, storms — these are all things that affect a species’ existence.”
And new threats continue to emerge. “There’s been a lot of discussion about how global climate change affects ocean acidification, and now there’s emerging evidence that the even greater threat is reduced oxygen levels,” says noted conservationist William Laurance of James Cook University. A study published last month found that ocean deoxygenation could have a major impact on zooplankton, one of the building blocks for the ocean food web. Deoxygenation also causes increased algal growth, like the red tides that choked the coasts of Florida this past year and killed hundreds of manatees and tens of thousands of fish.
“Changes in ocean composition will be a large-scale driver of mortality,” Laurance says. “Some people are calling this ‘the great dying.’ ”
A related issue in the Arctic also appears to be another emerging threat. According to the just-released “Horizon Scan of Emerging Issues for Global Conservation in 2019” (the tenth annual edition of this study), climate-change induced release of carbon from polar ice will further worsen global warming, while the release of mercury from thawing permafrost will create a toxic threat for animals, plants and soil.
Meanwhile, on top of the obvious weather-related changes, climate change could create an additional unexpected threat to some species: wildlife trafficking.
“Some species will undoubtedly decline as a result of climate change, making them rarer and thus potentially even more desirable by those who trade in them,” explains Richard Thomas, global communications coordinator for TRAFFIC, the anti-wildlife-trafficking organization. “Addressing wildlife trade issues and promoting sustainable harvesting are likely to become more important than ever,” he says.
The (tiny) bit of good news related to climate change? Because so many scientists are studying it, we’re learning more and more about its effects.
“I think research showing when, where and how species are able to adapt to some changes is promising,” says amphibian biologist Karen Lips of the University of Maryland. The more we know about exactly how climate change threatens certain species — or about how they can adapt to it — the better we can do at protecting them from extinction.

Politics in the Trump Era — and Beyond
Among the greatest threats to wildlife are the Trump administration and similar politicians around the world, such as Brazil’s new far-right president, Jair Bolsonaro, who took office last week and immediately moved to undermine indigenous rights in his country.
“The new president in Brazil could unravel 50 years of progress for species, tropical forests and indigenous people,” says Lindsay Renick Mayer, associate director of communications for Global Wildlife Conservation. That could be devastating to one of the world’s most biodiverse regions on the planet, which is often referred to as the “lungs of the Earth.”

Mayer adds that the recent election in Madagascar could be just as bad. Former president Andry Rajoelina, whose previous tenure was marked by a dramatic increase in illegal logging, deforestation and biodiversity loss, was reelected last month, although as of press time the election remains mired in protests and accusations of fraud. “The risk of losing the amazing biodiversity of Madagascar is always a big story and it could get worse now,” Mayer says.Getting back to the Trump administration, many experts worried about how things will play out for this country’s wildlife in the year ahead.
“The federal government is shirking its duty to protect species and commit to conservation programs,” says Johnson of the Union of Concerned Scientists, who points to three potential rule changes would diminish the effectiveness of the Endangered Species Act and other conservation regulations, among many other attacks against the laws. “This, in addition to funding cuts for species listings, will put a strain on conservation efforts,” she says.
Johnson expects funding to remain an issue in 2019, as will further attacks against the Endangered Species Act.
Others echoed those thoughts and fears about the ESA. “I think our current administration has shown that the environment and conservation are not high priorities,” says Lips. “I think that has a dampening effect on the actions of the federal agencies.”
There’s a potential positive side to this, she adds: “I have heard, however, that historically this produces increased donations to NGOs and increased activism by citizens.”
Indeed, that may have also helped inspire last November’s “blue wave,” the newly elected officials from which took office this month. Many of our experts expressed cautious optimism about these new government representatives.
“I think one of the biggest stories of the year is going to be what Democratic House oversight of the Trump administration can do for environmental policy,” says shark scientist David Shiffman. “Each individual thing they do will be very subtle and maybe you won’t even know what’s happening on time, but the aggregate effect, I think, will be slowing down a lot of the harmful decisions made by this administration.”

Roads to Ruin, But a Push to Preserve
But outside of Washington, things are speeding up. New road and infrastructure projects, many backed by Chinese investment, are currently being carved into critical habitats in Indonesia, Africa, the Amazon and other regions. Much of this stems from China’s Belt and Road Initiative, a development strategy to build extractive industries in 70 nations around the globe along with overland roads, ports, railways and pipelines to exploit them.

“We’re experiencing an avalanche of new infrastructure projects,” says Laurance, who points out that the Initiative has at least 7,000 developments planned or underway. One of the most notorious projects is a gigantic hydroelectric dam that could wipe out the newly discovered Tapanuli orangutan (Pongo tapanuliensis) in Sumatra.
Meanwhile, a similar — if not even more extensive — proliferation of illegal roads is being constructed around the world by loggers, miners, poachers and other extractive industries. These activities threaten everything from elephants and tigers to insects and rare plants.
One big problem is that conservationists don’t always know where these roads — legal or otherwise — are being built, and without that information it’s impossible to protect species from development.
“It’s actually really difficult to try to get even basic maps of where roads are,” Laurance says. Right now he and his team pore over satellite images by hand, looking for signs of new disturbance — not an easy prospect when images vary by surface, shadowing and other factors. “Our group has spent something like a thousand hours trying to map these roads,” he says.
Their results of their labor-intensive work are rather shocking: “For every kilometer of legal road, we’ve mapped around three kilometers of illegal roads,” Laurance says. “That’s a very rough average, but it gives you an idea of the magnitude of the problem.”
Laurance has issued a call for help to develop a software tool to automate the road-discovery process. “We’ve got an urgent need to detect the roads and tell governments, look, here’s where there’s illegal activity,” he says.
Without that, conservation — and species — will lose ground every day. “The bottom line is we need to be able to keep track of roads in real-time, on a global scale, and especially in developing countries,” he says.
As this road-building goes on, governments around the world face a tight deadline to protect some of their most pristine wildlife habitats — or at least say they’re doing so. The signatories to the Aichi Biodiversity Targets have until 2020 — next year — to meet 20 conservation goals, including conserving “at least 17 percent of terrestrial and inland water, and 10 percent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services.”
Most countries haven’t come close to that goal yet. Many of the experts we spoke with expressed hope that the tight deadline will result in some good, quick land and water protection that could protect countless species, but cautioned that these efforts should be watched carefully to make sure they truly protect key habitats and that they offer connectivity between disparate species populations.
The oceans will also be a big part of the Aichi targets. “You’ll probably see a lot of new, large marine protected areas established in the next year,” says Shiffman. He cautions, though, that some of these could be established in places where there’s no fish or other species to protect, or no system in place in which to protect what’s there. “They could end up being paper parks — parks in name only,” he says.

A Host of Other Issues

Here are a few more factors predicted to play a big role in 2019.
First, we continue to learn more about how plastic waste affects wildlife and the environment. Most recently, a study found that 100 percent of sea turtles had plastic or microplastics in their digestive systems. With more and more plastic being produced every day, this will be a major focus of research and conservation the coming year.
Meanwhile many experts also expressed fear about emerging diseases, like those affecting bats, frogs and salamanders.
“Emerging diseases are increasing in numbers, impacts, and in incidents, and are likely to cause greater losses of species,” says Lips. “They don’t often get the attention that climate change does, and the time scale is accelerated.”
Lips also noted that it’s often hard to get funding and other support for these growing problems because they’re less in the public eye. “People and the media tend to focus on the current emergencies rather than the slow, long-term problems because we are not very good at maintaining focus and attention,” she says.
The threats of poaching, snaring and wildlife trafficking will also remain significant around the world, as the forests of southeast Asia and the plains of southern Africa became emptied of their animal life and as “valued” species such as tigers, rhinos and pangolins face ever-increasing pressures.
Right now this activity is all illegal, but that could change in the blink of a pen stroke. “We need to watch out for the pro-trade agenda” like this past year’s attempt by China to legalize the medicinal trade in rhino horns and tiger parts, cautioned Rhishja Cota, founder of the wildlife advocacy organization Annamiticus. This may also mean keeping an eye out on the Trump administration’s continuing efforts to promote big-game hunting and resulting trophy imports by its wealthy patrons.

Finally, as habitats shrink and poaching and other threats take their toll, a growing number of species are likely to benefit from last-gasp captive breeding, either to boost their wild populations or to keep them alive once their habitats have disappeared. The red wolf and Florida grasshopper sparrow captive-breeding programs may save those species from extinction in 2019. Another species starting the year off on better footing is one of the world’s rarest birds, a duck called the Madagascar pochard (Aythya innotata), just returned to the wild after 15 years thanks to a captive-breeding program in Scotland, of all places. Other incredibly rare species likely to benefit from similar programs this year include the Sumatran rhino (Dicerorhinus sumatrensis) and maybe even the rarely seen saola (Pseudoryx nghetinhensis).
“We haven’t had a camera trap photo of saola since 2013 and no biologist has ever seen one in the wild,” says Mayer from Global Wildlife Conservation. “But the Saola Working Group and partners are hoping to detect saola and begin to catch them next year for a conservation breeding program in Vietnam. Next year could be the year we rediscover this species and work toward breeding it.”

The Countdown Begins
The year 2019 has just barely begun, but experts warn us that the opportunity to make a difference on these issues is already running short.
“I don’t want to sound too bleak, but time is literally running out for the world as we know it,” say TRAFFIC’s Thomas. “The Earth simply can’t take the punishment of relentless over-exploitation of its natural resources, poisoning of its atmosphere and pollution of its oceans. We need to put aside political differences and work together to do something about this catastrophic situation — and quickly.”

Climate Change: Focusing On How Individuals Can Help Is Very Convenient For Corporations

The Conversation

To do list. Joel Carrett/EPA-EFE
What can be done to limit global warming to 1.5°C? A quick internet search offers a deluge of advice on how individuals can change their behaviour. Take public transport instead of the car or, for longer journeys, the train rather than fly. Eat less meat and more vegetables, pulses and grains, and don’t forget to turn off the light when leaving a room or the water when shampooing. The implication here is that the impetus for addressing climate change is on individual consumers.
But can and should it really be the responsibility of individuals to limit global warming? On the face of it, we all contribute to global warming through the cumulative impact of our actions.
By changing consumption patterns on a large scale we might be able to influence companies to change their production patterns to more sustainable methods. Some experts have argued that everyone (or at least those who can afford it) has a responsibility to limit global warming, even if each individual action is insufficient in itself to make a difference.
Yet there are at least two reasons why making it the duty of individuals to limit global warming is wrong.

Individuals are statistically blameless
Climate change is a planetary-scale threat and, as such, requires planetary-scale reforms that can only be implemented by the world’s governments. Individuals can at most be responsible for their own behaviour, but governments have the power to implement legislation that compels industries and individuals to act sustainably.
Although the power of consumers is strong, it pales in comparison to that of international corporations and only governments have the power to keep these interests in check.
Usually, we regard governments as having a duty to protect citizens. So why is it that we allow them to skirt these responsibilities just because it is more convenient to encourage individual action? Asking individuals to bear the burden of global warming shifts the responsibilities from those who are meant to protect to those who are meant to be protected. We need to hold governments to their responsibilities first and foremost.
A recent report found that just 100 companies are responsible for 71% of global emissions since 1988. Incredibly, a mere 25 corporations and state-owned entities were responsible for more than half of global industrial emissions in that same period.

Most of these are coal and oil producing companies and include ExxonMobil, Shell, BP, Chevron, Gazprom, and the Saudi Arabian Oil Company. China leads the pack on the international stage with 14.3% of global greenhouse gas emissions due to its coal production and consumption.
If the fossil fuel industry and high polluting countries are not forced to change, we will be on course to increase global average temperatures by 4°C by the end of the century.
If just a few companies and countries are responsible for so much of global greenhouse gas emissions, then why is our first response to blame individuals for their consumption patterns? It shouldn’t be – businesses and governments need to take responsibility for curbing industrial emissions.

Governments and industries should lead
Rather than rely on appeals to individual virtue, what can be done to hold governments and industries accountable?
Governments have the power to enact legislation which could regulate industries to remain within sustainable emission limits and adhere to environmental protection standards. Companies should be compelled to purchase emissions rights – the profits from which can be used to aid climate vulnerable communities.
Governments could also make renewable energy generation, from sources such as solar panels and wind turbines, affordable to all consumers through subsidies. Affordable and low-carbon mass transportation must replace emission-heavy means of travel, such as planes and cars.
More must also be done by rich countries and powerful industries to support and empower poorer countries to mitigate and adapt to climate change.

All of this is not to say that individuals cannot or should not do what they can to change their behaviour where possible. Every little contribution helps, and research shows that limiting meat consumption can be an effective step. The point is that failing to do so should not be considered morally blameworthy.
In particular, individuals living in poorer countries who have contributed almost nothing to climate change deserve the most support and the least guilt. They are neither the primary perpetrators of global warming nor the ones who have the power to enact the structural changes necessary for limiting global warming, which would have to involve holding powerful industries responsible.
While individuals may have a role to play, appealing to individual virtues for addressing climate change is something akin to victim-blaming because it shifts the burden from those who ought to act to those who are most likely to be affected by climate change. A far more just and effective approach would be to hold those who are responsible for climate change accountable for their actions.
